NextPower delivered a strong quarter, characterized by continued bookings momentum and backlog growth, operational discipline and execution, and significant progress in the expansion of our technology platform. We achieved a record quarterly revenue of $935 million with adjusted EBITDA of $233 million. Backlog grew to over $5.5 billion, reflecting healthy customer demand and booking strength across both our core tracker business and our expanding portfolio of non-tracker products. On top of the $5.5 billion, NextPower Energy Storage brings over $300 million of additional backlog. We demonstrated continued progress with our long-term strategy of solving customer problems and delivering tangible value and performance. For most of our history, this meant developing tracker products that helped customers lower LCOE, accelerate installation, improve reliability, reduce risk, and increase energy yield. That approach led to global market leadership in solar trackers. According to Wood McKenzie for 2025 Tracker Market Share, NextPower was recognized as the number one solar tracker company in the U.S. and globally for the 11th consecutive year, growing share to 55% in the U.S. and 30% worldwide. by innovating tracker solutions that solve complex project challenges and improve financial outcomes we have earned trust and repeat business from our global tier one customer base and deployed our technology across projects totaling more than 160 gigawatts each project deepens our customer relationships and gives us greater insight into evolving needs of utility scale solar and storage customers. Those insights guide how we invest, both organically and through disciplined M&A, to enhance the value we can deliver to our customers. Customers continue to ask us to do more as utility-scale solar storage and critical power infrastructure projects become larger and more complex. With the acquisition of Prevalon, which closed last Monday, we launched next power energy storage. Prevalon brings us a proven team with an excellent track record across six gigawatt hours of turnkey storage solutions, spanning applications from dispatchable peaking power to data center stabilization, serving blue chip customers. Solar and storage are highly symbiotic technologies for electric grids, enabling low cost energy and rapid capacity deployment for dispatchable firm power. Energy storage also represents a significant growth vector and opportunity for next power, as it is projected to grow at 33% CAGR from 2025 to 2028. Since our last call, we also announced the pending acquisition of Zimmermann PV Steel Group, a very well-respected company based in Germany with an excellent European footprint. Upon closing, Zimmerman is expected to expand NextPower's offering with five new product lines, extending the company's reach into 15 additional countries and creating cross-selling opportunities for NextPower eBoss, power conditioning systems, and batteries. These transactions follow our customer-focused playbook, identify critical pain points, invest in differentiated technology, scale through NextPower's global footprint and trust relationships, and reinvest to strengthen the platform. As we execute on this strategy, we believe we can improve customer outcomes, increase our project participation scope, strengthen NextPower's competitive moat, and generate attractive long-term returns for shareholders i also want to proactively address questions around tuesday's announcement by the fcc related to imported inverters next power launched a power electronics business to solve customer needs in inverters which include better operating performance stronger domestic manufacturing enhanced cyber security and support from an investment grade u.s company that has a strong product service culture. Our new inverter business satisfies these needs and helps to further de-risk customers as we may see additional U.S. government restrictions on overseas inverters. We're pleased to announce today that our acquisition of the Apex inverter business has closed and that our product has achieved Underwriters Laboratories UL1741SB certification. We are further accelerating our U.S. manufacturing build-out across multiple locations. We expect deliveries to begin in early 2027 and plan to have over 10 gigawatts of U.S. capacity online next summer. Our UL-certified APEX inverter is designed to enhance cybersecurity using site-level optical fiber communications and is designed to meet all government requirements. Customer response to our inverter technology, manufacturing, cyber, domestic manufacturing, and service plan has been very strong. We're doubling down on ramp plan for these essential products and services with the goal of having the highest availability operating inverters for solar and storage power plant owners. The current market environment represents a structural tailwind for our business. Global electricity demand continues to accelerate, driven by electrification, industrial growth, artificial intelligence, data centers, and the need for more reliable and resilient power infrastructure. Solar and storage are the fastest, lowest cost, and proven ways to add new capacity. As this market moves forward toward terawatt-scale annual deployment volumes, customers need partners that can deliver high-performing, reliable energy infrastructure solutions at scale. We believe NextPower is uniquely positioned to meet that demand. We will be hosting our second Capital Markets Day on November 16th at RE Plus in Las Vegas, where we will provide an update to our 2030 outlook that will reflect a material acceleration due to our strong market momentum, recent strategic acquisitions, and exemplary operational execution. We look forward to seeing many of you there. With that, I'll turn it over to Howard.
Thank you, Dan. Q1 was another great quarter for NextPower, marked by record revenue, strong customer bookings and backlog growth, and operational execution. We continue to see a flight to quality in the market and increasing validation of our platform and bundling strategy. Customers are choosing NextPower because of our technology, execution, supply chain, bankability, and customer service. We believe these factors are propelling company growth and show up in our sales backlog and market share. We had another excellent bookings quarter with strong demand both in the U.S. and international markets. Tracker sales drove sequential backlog growth to a new record high. We are now also benefiting from meaningful sales and revenue contributions from non-tracker products, starting with eBoss, which serves as a proof point of how we are efficiently integrating and operationalizing acquisitions. We had record eBoss bookings in the quarter, and the product segment is on track to contribute well over $100 million of revenue for the year. Our eBoss offering has strengthened further with the recent UL certification of our unique and differentiated NX Power Merge solution. We have currently booked 850 megawatts of Power Merge with deliveries expected to begin in the current quarter. Secondly, our foundation's business is also growing with a 50% year-over-year increase in the quarter. Thirdly, our True Capture control system delivered record revenue and backlog in the quarter, reinforcing NX Power's industry-leading position. We are also pleased to announce in the non-tracker category that the APEX inverter is now UL certified and is applicable for both solar and storage markets. This certification paves the way for broad commercialization in the U.S. market and we are highly focused on rapidly building out a scalable and flexible supply chain for these products. Finally, we are very excited to add energy storage to the NextPower platform. With the launch of NextPower Energy Storage, we expand our ability to serve our solar customers with a broader set of integrated solutions while expanding our customer base to include hyperscalers, standalone storage developers, and a large range of utility customers. Now, moving to markets and the demand picture. The U.S. remains our best market globally. We are seeing continued positive demand signals as project pipelines are growing, getting permitted, and reaching construction. We have very strong and trusted customer relationships in the U.S., and this is helping us accelerate growth in our non-tracker business and puts us in great position for addressing the storage segment internationally we secured a tracker order for the largest solar plus storage project to date in australia a 721 megawatt project incorporating significant locally made steel content we also continue to expand our global customer footprint in the quarter taking our customer reach to over 50 countries the acquisition of Zimmermann PV, when closed, will extend our reach further with 15 additional countries. Zimmermann is a very well-respected brand with a fantastic team, with more than 20 gigawatts of cumulative projects and well-established customer relationships across Europe. Importantly, the acquisition of Zimmermann will expand our ability to serve a much broader set of ground-mount solar applications with their product portfolio. For example, roughly half of Europe's ground-mount PV installations are fixed tilt at about 25 gigawatts per year, and Zimmermann brings deep expertise in fixed tilt and other structural solutions that we expect will significantly increase our addressable market. Zimmermann's German headquarters and strong market position there are key strategic elements for us as Germany is projected by S&P to become Europe's largest solar market by 2030. Germany currently represents approximately 20 percent of Europe's ground-mount solar market mostly deployed as fixed tilt systems. We also see meaningful energy storage opportunities across Europe where installations are expected to grow rapidly. Over time, we believe that Zimmermann's sales channels and customer base, especially across Europe, can facilitate sell-through for Nextpower's product portfolio, including trackers, eBoss, power conversion, storage, and software. Turning to project timing and pricing globally, project timing generally remains manageable. As is typical in utility-scale solar, we continue to see some projects accelerate and others move to the right. And we manage those movements across a large and diverse portfolio of customers and geographies. Overall, pricing continues to track the broader solar cost curve and we continue to invest in R&D and scalable infrastructure to reduce costs while improving system performance. our culture is to relentlessly serve customers and deliver maximum value at competitive cost and pricing in summary our business fundamentals are strong and we are excited by the revenue and growth vectors we added with power conversion energy storage and e-boss solutions now in the mix demand is healthy our backlog is large and continues to grow execution visibility is solid
and we continue to strengthen our competitive position through innovation customer focus and operational excellence with that i'll pass it on to chuck thank you howard and good afternoon everyone overall q1 was another quarter of strong execution with results that reflected healthy and market demand, disciplined execution, and continued investment in long-term growth. For the first quarter of fiscal 2027, revenue was $935 million, representing 8% year-over-year and 6% sequential growth. Q1 adjusted gross profit was $342 million, adjusted gross margin was 37% and adjusted EBITDA was $233 million, representing an adjusted EBITDA margin of 25%. Q1 geographic revenue mix was approximately 83% U.S. and 17% rest of world. Our revenue mix remains predominantly solar tracker systems, but non-tracker products are becoming a more meaningful part of the business. In Q1, we recognized revenue from True Capture, eBoss, foundations, robotic solutions, and other platform offerings. Non-Tracker products represented approximately 14% of total revenue, reflecting continued customer adoption. Q1 saw solid execution that exceeded our gross margin targets of the low 30s, benefiting from IEPA tariff recoveries, higher relative U.S. revenue contribution, strong true capture revenue, partially offset by higher logistics costs. Adjusted operating expenses increased year over year as we expanded our platform and increased investment in research and development. This is consistent with the strategy we have discussed previously. Turning to cash flow and the balance sheet. Our strong balance sheet, cash flow generation, and ample liquidity remain competitive advantages. We closed the quarter with over $1.2 billion of total cash and cash equivalents with no debt. We generated $121 million of operating cash flow and $105 million of adjusted free cash flow in the quarter. We operate a capital-efficient business and remain focused on maintaining and improving our cash conversion cycle. Our investment-grade credit rating speaks to the strength of our balance sheet and capital structure, and it remains important to customers, suppliers, and project financing partners. Based on our Q1 performance, the strength and quality of our backlog, and continued demand across our core and emerging product categories, we are updating our fiscal 2027 outlook. We now expect revenue in the range of $4.1 to $4.4 billion, adjusted EBITDA in the range of $870 to $930 million, and adjusted diluted EPS in the range of $4.42 to $4.73. As previously communicated, our outlook includes planned investments of approximately $50 million dollars related to growth initiatives, primarily the acceleration of our entry into the power conversion market. I want to spend a minute on margins and returns. Our structural margin framework has not changed. We continue to expect gross margins in the low 30s and operating margins in the low 20s. Quarterly margins will fluctuate based on mix, tariff recoveries, ramping of new businesses and the policy environment but the long-term framework remains intact as we integrate recent acquisitions and scale new product categories we will see an impact to EBITDA and margin percentages in many organic initiatives or acquisitions certain costs will come ahead of revenue as we build engineering manufacturing go to market and service capabilities we are making these investments where we see strong customer pull, clear strategic fit, and attractive financial returns. eBoss is an early proof point. A little over a year after acquiring and launching that product line, we have delivered multiple quarters of record bookings and revenue and seeing strong attach rates. And as Howard pointed out earlier, remain on track to generate well over $100 million of revenue this year. Prevalon is another example of our approach. A meaningful portion of the consideration is tied to future profit targets and management incentives that are aligned with cumulative profit. We are not relying on speculative upside or large unproven cost synergies to justify the transaction. We acquired proven deployments, real customer relationships, backlog, lifecycle service capabilities, and a platform we believe can scale through NextPower's customer relationships, engineering, supply chain discipline, and execution model. As NextPower scales, we believe investors should evaluate us on both absolute profit dollars as well as margin percentages. The objective is not to dilute returns to buy revenue. We are focused on sustaining structural margins on a larger revenue base while growing adjusted EBITDA dollars, free cash flow, and return on invested capital over time. Finally, on capital allocation. Our priorities remain consistent. First, we continue to prioritize organic investment and new products and services. Second, we pursue disciplined M&A that strengthens our technology platform and creates customer value. returning capital to shareholders remains the third pillar of our capital allocation framework with our board approved $500 million share repurchase authorization. We have increased confidence in our ability to deliver sustained growth and profitability while continuing to invest in innovation and long-term value creation. And with that, we'll take your questions. Operator?

We will now begin the question and answer session. If you would like to ask a question, please raise your hand now. If you have dialed in to today's call, a reminder to press star 9 to raise your hand and star 6 to unmute. Please stand by as we compile the Q&A roster. Your first question comes from the line of John Wyndham with UBS. Your line is open. Please go ahead.
Hey, this is David Cho on for John Wyndham. Thanks for taking my question and congrats on the quarter. I know you mentioned the FCC inverter ban briefly. But I was just wondering, assuming you made the decision to accelerate investment in the inverter segment prior to that announcement, just wondering how do you view or how do you kind of view the change in the scale of the opportunity for you in that product segment post the announcement or how incremental is that to kind of your long-term outlook for market share in inverters?
Hi, David. But Dan Sugar, thanks for the question. So, you know, we keep saying this and it's just very basic and so true. We ask customers, what are your greatest, you know, pain points? What do you need help with? And it comes back often inverter power conditioning unit, those things. And so we actually made a decision over two years ago to really launch a family of products in the inverter business to serve solar and power conditioning business, to serve energy storage. So we have a tremendous amount of momentum on organic internal product families. And then we also wanted to double down on that, and we did the acquisition of the Apex product line, and we couldn't be more pleased with that. Let me be clear about what our objective is. NextPower will deliver to the market the most available inverter and power conditioning products in the industry. That's our objective, and we will get that done. And what that means is from an owner standpoint, these systems are online, okay, when you look back after a year or five years, what have you. And it's not rocket science. I could take you to systems we did 20 years ago with really inverters, IGBTs, inverters that are still operational. So in order to do this, you need to have a great product, a great service model, spare parts, operational excellence, and the right kind of service culture. And we're going to do that. So in response to as we've been rolling this out and preconditioning the market, we've seen very strong demand and feedback from our customer, which is why at our last earnings call, you know, we announced we're putting this incremental $50 million in, which is, you know, real money. And we've hired some of the best and the brightest organically, and then we're extremely pleased to bring the Apex and legacy Ziggur technology team led by Antonio Pavetta and Jacob Marshall in the United States to the team. And so what we're seeing is customers are also really valuing domestic production. They're valuing cybersecurity. This also addresses fiat concerns. We're going to have a portfolio of product and supply options for these segments or these applications available to the market. and it's also synergistic with the storage business that we announced completion of the acquisition last week.
Operator
Thank you. I'll close it on. And your next question comes from the line of Brian Lee with Goldman Sachs. Your line is open. Please go ahead.
Hey, guys. Good afternoon. Thanks for taking the questions. I have two, so I'll just try to put them both in here. One, there's been a number of M&A deals here, obviously. So would be curious, Dan Howard, if you guys have any comments you can make early read on integration efforts, realization of synergy potential, anything you can quantify. I mean, it does sound like margins may be impacted negatively near term, but then should be back to normal by end of fiscal year end. And then related to that, just curious how your direct access, visibility discussions, however you would characterize it with hyperscaler and data center customers has evolved here with the more robust portfolio and you know maybe how quickly you expect to realize some of the opportunities across that customer segment and then maybe in what product category specifically thanks guys sure i'll take the first part brian related to the acquisitions and how the integration is going how it'll take the second part uh related to the hyperscalers in that market segment So first, we have a history of success with M&A.
We did the BrightBox machine learning acquisition 10 or 11 years ago. That really helped us develop our True Capture and NX Navigator suite of products, which has been an overwhelming success in use on many hundreds of power plants, extremely material to our financial results, but importantly to the customer project. Starting about three years ago, we did a number of smaller acquisitions. Those have been fully integrated. Those are more tuck-in technology acquisitions. We did Ojo on the foundation. We have many gigawatts of that under fulfillment. That's going great. Complementary technology on the foundation business that customers are really valuing. And, you know, some of this stuff's hard. You have to invest. It takes a few years to operationalize and be able to really get to both volumetric scale, but also tune these businesses up where they're actually hitting the financial metrics you want. So, I mean, that's going great. We've done a number of additional earlier stage businesses. And Chuck, in his earlier remarks, mentioned, for example, our eBoss business. We closed that just about five quarters ago. We're at sort of a $100 million annualized run rate, which is double what that company did in the 30-year history. And we just announced our new UL-listed product, Power Merge, which brings the best of both schools of thought through electrical balance system to the market. And we've seen great results there. So, you know, it really comes to putting your shoulder into these things, sweating the details, getting the best people to run these businesses, empowering them, and then bringing those forward to customers where we're adding value. And, you know, I think our program is going extremely well. What's different about the Prevalon acquisition is that we had a very mature team that had done about 38 projects with very good references from customers. I was just out at a large utility scale site last week with the team, a 200 megawatt, 800 megawatt hour site that was brought online in under a year. The very sophisticated utility customer was extremely pleased with the performance. So we don't need to integrate those as much because that product line can run. And the last one in that M&A family, the large one that we announced last quarter was a definitive agreement to acquire Zimmerman in Germany, which is a very well established, respected, stable revenue, cash flow generating company in Germany that we don't need to do the level of integration we have with the other businesses. So that's how we've thought about that program. Howard, can you address the hyperscaler question? Sure. So, hey, Brian.
So we are serving hyperscalers both indirectly and directly. And by indirectly, I mean we're working with IPP owner developers who have contracts with hyperscalers, and we're supplying equipment to them. Now that we have a full platform of solar and storage, we can offer much more value for both hyperscalers and our IPP developer partners. That's indirectly, and then directly, we are working with hyperscalers directly. One product that Prevalon, now NextPower Storage, has is hybrid OS. It's a power stabilizer that provides continuous power, can respond to data center demand fluctuations that are less than 10 milliseconds, really fast response, and working directly with hyperscalers and what they're doing on their side of the meter on those kinds of applications. So, people ask, is hyperscaler market and data center market and demand market for electricity real? It's very real. We're seeing expanding pipelines to serve this market segment and closing business on that basis. So we're really excited about that. I just wanted to add that today we announced the closing of the inverter acquisition we made in power conditioning system acquisition. Dan noted that that acquisition serves both solar and storage. So there's some synergy there. You asked about synergies, Brian, and that's one of them, taking that inverter power conversion technology from one company and porting it through our next power storage acquisition and Prevalon. So quite excited about that. Thank you.
Operator
And your next question comes from Mark Strauss with J.P. Morgan. Your line is open. Please go ahead.
Great. Good afternoon. Thank you very much for taking our questions. i appreciate you guys are giving us the the percentage of your revenue it's coming from the non-tracker business is there any other color that you can provide us though as far as like the the percentage of your tracker projects that are coming with other technologies maybe kind of the average number of offerings or solutions per project kind of what that looks in your bookings and maybe how that's trended over the last couple of quarters and then just the quick follow-up if I can get it out there. Chuck, I just want to make sure the $50 million incremental investment in power conversion, is that in line with what you were talking about back in May when you announced the deal? Or is this incremental on top of that? And so we should be thinking about $100 million now. Thank you.
Thanks, Mark. I'll go first. This is Chuck. It's the same $50 million. We're excited that the power conversion business closed today. And so that investment really started a little bit last quarter, but for the most part, it's kind of over the next four quarters. It's the same numbers, though, not incremental to what we announced in May.
Okay, this is how I'm really pleased with the progress in porting in more products alongside our tracker platform, including foundations, which grew 50% year over year. in revenue for the quarter. And then our eBoss business, Dan mentioned it in his previous answer, that that's really going extremely well, 100 million plus revenue run rate for the year, which is beginning to become, well, it's a meaningful contribution to our annual revenue and growing. The attach rate on eBoss, I think is particularly striking for us. And it's, it's exceeding the overall attach rate that we noted in our remarks of 14%. So we're really happy with the progress on eBoss and everything so far points to an affirmation of our strategy, which is to offer a fully engineered solution, an entire bundle where we're wringing out costs and increasing yield. Just, you know, integrating our foundations with our trackers, we were able to reduce install time by 20%. Part of that, we eliminated all the fasteners between the foundation and the tracker. So that's another proof point of what we can do to optimize system costs and performance and provide a better solution for our customers. Thanks, Mark.
Operator
And your next question comes from Phil Shen with Roth Capital Partners. Your line is open. Please go ahead.
Hey, guys. Thanks for taking my questions. First one here is on your margin expansion. You highlight in your quarter or in the shareholder letter that this was driven in part by True Capture and tariff recoveries. I was wondering if you could split that out and specifically call out how much True Capture benefited you guys there. And then ultimately, can you give us a more detailed update on True Capture? I know at the IPO, you guys were a little bit hesitant on that, but you've had some time now, a few years here to ramp up that volume. So I was wondering what percentage of your install base has true capture and then as you book new business what's the attach rate of true capture uh there given the strong margins it's uh it'd be great to understand uh what kind of impact true capture is having thanks yeah phyllis chuck i'll go first on the on some of the details and howard can fill in attach rates um so true capture historically was two percent of revenue um we're not giving the exact number, but it's gone higher.
So the overall revenue from True Capture has accelerated. We had a great quarter and it's tied to commissioning. So you'll see some quarters it goes up, some that may be in line. But we expect a very strong year for True Capture. Q1 was strong. But the real kind of overall beat on margins was we had pretty significant IEPA recoveries. And there's still more that we'll get in in q2 and some beyond possibly but that was a real benefit and there was a bit of a headwind on freight that kind of offset that a bit but i would look in our guide overall was you know kind of low 20s uh operating margins and we you know delivered 25 percent and that overachievement was primarily tariff recoveries then offset a little bit by freight and logistics howard do you want to talk about the attach rates sure um first i want to hum a few bars on True Capture, which we love and adore because it represents the best of what we do as a company.
We've been working on it for about 10 years. It's a really hard thing to do, which is to optimize the performance of every single row of trackers in a field. And there are thousands of tracker rows in every field typically uh for the larger fields and um we operate each one independently to maximize yield and that's what true capture does um and it does it in several different ways and we've proven it third-party engineers have have proven it that it works it's validated and we have many tens of gigawatts of true capture installed with validated performance and we are seeing increasing attach rate for it because over time um the it becomes even more valuable the more you have uneven terrain and more difficult uh uh locations to install the power plant. And so, operating the power plant in a reliable way that maximizes yield is becoming more challenging, but our true capture control system does that. And so, we're not publishing attach rates, but I can tell you that it's going up. When we did the IPO and did the roadshow, we said it was about 1% of revenue. then we've given indication that it's two percent of revenue well i can tell you in the quarter it was higher than that and um and so the attach rates are going up for that and it is important phil it's very insightful question um and uh much appreciated thanks hard quick follow-up here uh on bookings uh in the quarter uh can you guys share what the mix was between the different products.
I know the revenue you guys talked about non-tracker was 14%. On the bookings, can you do the same? And then also on a go forward basis, you guys have been pretty steady in this $1 billion per quarter kind of bookings level. Do you see potential for that to accelerate or should we continue to expect this billion dollar cadence? Thanks.
I'll take the first part to fill in the numbers, and Howard can fill in more color. We raised our backlog number from 5.25 to 5.5 billion, over 5.5 billion. We also want to be clear that our energy storage business, which just closed in July, adds significantly more than 300 million on top of that backlog.
We don't break out the details of the of the over 5.5 billion but howard you want to add some color well i'll just say that um i like how you framed the question phil and i'm going to affirm that we did book more than 1 billion dollars well over for the quarter we had a great bookings quarter and it is uh was supported both by a strong u.s and strong international sales and strong sales coming from non-tracker business, but we're not breaking out precisely what the mix is, but directionally meaningful, very meaningful contributions from the non-tracker part of the business.
Operator
And your next question comes from the line of Moses Sutton with BMP Paribas. Your line is open. Please go ahead. A reminder that you may need to hit star six to unmute.
Thanks for taking my question and congrats on beating, well, every quarter. um so 10 gigawatts of u.s inverter capacity uh good push i don't know to eight percent of 2028 revenue if you start selling that out is that the case is that sort of the directional view here and similar to trackers would you actually expect to have extra capacity and inverters on hands for like surge shipment needs and i guess my second question you know what other areas are you guys looking to conquer next you know you're getting into power conversion there It could be medium-voltage transformers. It could be commercial solar battery kits or integrators, just other areas that are on your mind. Thanks for taking my questions.
Yeah, thanks, Moses. I think what you've seen in the past is we don't screw around when it comes to supply chain. uh from a capacity from an operational execution from you know having raw materials and uh you know our balance sheets really supports being able to to to accomplish all the above um so we're going to size the um domestic production capacity in response to um what you know the market needs are i also want to just highlight that the energy storage business the prevalent business they do work with third-party uh power conditioning um manufacturers have great relationships there we're going to keep respecting those relationships on the power conditioning side with storage the business unit can either use an inverter that we would make at the company or a third-party inverter as long as it's a high-quality product that's supported with on-time delivery and great service. So that particular business unit will be free to find the best solution for the customer. But for our internal program to build U.S. inverter capacity, we are very pleased. We We brought Rob Vingy in as our chief operating officer. We have a long, and he is, his top priority is that. We have a long experience with Rob. I first met him 20 years ago with Howard. We were on the roof of the Sun Power, Solar Power cell line in Manila, in the Philippines. Rob scaled thousands of buildings with Amazon and is one of the top operational, well, he is the top operating person we know in the industry period. And so we're very pleased to have him join the team in the last few months. And he's working with our existing team with some of the new folks that we've brought on through the acquisitions, and we're adding some additional team members. So we have the resources, we have the strategy, we have the capital, and we've listened to our customers. These inverters and power conditioners have been the Achilles heel of solar and battery, and those days are going to be over. We are going to address that issue and deliver the most reliable and available set of products, period. And our customers are begging us for this, and we're going to fulfill that. And I think it's hard, but i don't think it's rocket science we're going to get it done so in terms of you know we don't we're not really thinking about um you know what percentage of the revenue is it exactly we're just focused on um the business case uh ultimately that product family is actually a higher margin business than the the our our tracker business um and it will if we deliver operational excellence there, which we will. We hope that it lands and performs at a higher margin, part of our overall portfolio of products and services we're bringing to the market. But what we're most focused on is meeting customer expectations with schedule, with product performance, commissioning, reconstruction, design, support getting through the utility process, and so forth, and then having both a very strong quality and very strong reliability program at the company to be able to support that operational performance. If we do all the above, the sales, the profitability of those units will then be a byproduct of us doing our job.
And we think not only is this an important thing for our customers and NextPower, but we think it's an important thing for the industry and um so we're going to really lean in on this and uh provide this this portfolio to our customers and um part b i'll just start dan if you want to fill in you were asked about other m a um as dan noted we formulated our platform strategy more than two years ago we've really executed on it to evolve beyond the tracker to provide a full turnkey solution for both solar and storage. We have the major, major pieces in place now with the closing of the Prevalon deal for storage and the Apex Digger acquisition. But there's more to do. There is more to do and more possibilities there, as you noted, Moses. But Dan, do you want to add to that?
Yeah, I mean, look, we're continuing to invest well over $100 million a year organically in our R&D and develop a suite of products there. Again, we're listening to what are opportunities that customers have to help them with their IRR on their PowerPoint investments. If there's something we need to do, we'll take it on. If we can develop it organically, that's usually the best thing to do. If we need to do an M&A to accelerate time to market and bring additional experience into our company that we don't have, as we did on the energy storage business, we'll do that. The only thing we are committed to is a fully informed decision, and that is objective and delivers value to the customer and also shareholder value.
Thanks, Moses. Thanks, Preval.

And your next question comes from the line of Dylan Nassano with Wolf Research. Your line is open. Please go ahead.
Yeah, thanks for taking my question. So now that Prevalon is closed, I just was hoping we could get an update on, I guess, the cell procurement strategy there and specifically, I guess, just the appetite around offering a U.S. domestic product. And if I could just sneak one more in just on the guidance, I mean, I see the bottom end of the range was raised. I'm assuming visibility improved since our last update. Just any color on why not raise the top end here? Is there anything specifically that you're kind of being cautious on?
Yeah, okay, I'll do the first half. So the former Prevalon team, now Next Power Energy Storage team, has, as I mentioned, delivered approximately 38 projects to the market. I personally spoke to eight of the legacy customers, including a very large hyperscaler that the team is currently fulfilling a project over one gigawatt with, and that's going really They have a, I'll say, a portfolio of supply options available to meet the customer's domestic content requirements just as we do on the tracker side and our other product side with our other products at next power um i haven't heard any customers uh actually last week we went we met with over 10 customers speaking a lot about energy storage i well with every customer we spoke about energy storage and um there we didn't hear any requirements from them that we can't we can't meet And so it's exciting that just as in solar with solar panel factories being built out in the U.S., we're also seeing additional battery factories being built out in the U.S. And so we have a good position today, and we expect that to grow as the capacity grows and customer needs to grow. Chuck, can you take a second part?
Certainly. Dylan, we had a really strong Q1 and feel like we've got the wind at our backs and are set up for a great year. We did our Q4 earnings call in mid-May where we outlined our annual guidance. A month or so later, we announced the Prevalon transaction and materially raised top and bottom. And then here we are, you know, a month and a half or so later, raising the bottom end of the range. But we come in there with strong conviction. Why? Well, we see revenue increasing throughout the year. We noted in the shareholder letter that we'll see modest sequential increases in revenue throughout the year. But importantly, we did not add an outlook for Zimmermann, the company in Germany that has a very strong business and strong profitability, strong cash flow. That's not in our outlook because we're not exactly sure in the timing of when that will close. Prevalon, we did because we had strong conviction on when that would close and it was basically right on target. And so we are set up for the back half of the year to have an increase likely tied to Zimmermann being closed. But I'd say it's just Q1. We just finished our first quarter. We still have three quarters to go. So we want to be prudent with our overall outlook. Thank you, Dylan.

And your next question comes from the line of Christopher Selder with Truist. Your line is open. Please go ahead.
Hey, thanks so much for taking my question here. I'm curious. It was really helpful, you guys framing the inverter opportunity set. As we're looking at storage, are there any concrete numbers you can give around the gating factors there, be it cell supply, be it some of the module capacity or containers that you could kind of talk through?
Yeah, thanks, Christopher. First, I want to just pull back and compliment the team, the Next Power Energy Storage team, the CEO of that, Tom Cornell, and Ben Honnold, the CFO, and the Chief Technology Officer, Alejandro, for how they've really brought together a great set of products to the market. They have both a DC block and an AC block solution in the market. And so it really addresses, there's 10 use cases in battery energy storage, and they address eight of them. And there's, you know, we spoke about this power stabilizer application for data centers, something none of us were talking about a few years ago. And here they are fulfilling one of the largest projects in the country with that. So, you know, we just closed last week, and we're out speaking with customers now. So, you know, we'll certainly unpack this in much greater depth at our Capital Markets Day on November 16th. But what I'll tell you is that I see no impediments to being on the company from either a supply, design, financing standpoint to be able to satisfy customer needs. the battery segment we put in the shareholder letter latest data that we have is it's growing at a 33 percent CAGR through 2030 based on the latest forecast and we're seeing it a lot of our legacy virtually all our legacy customers on the solar side are doing storage we're seeing a lot of pure place storage companies we're seeing utilities go out for bid because it's a way to not only arbitrage power from the middle of the day to later in the evening or in the morning, but also it's a way to deal with limited transmission capacity on the electric transmission side. If you analyze how little transmission is being built in the United States, I'm talking of electric transmission and sub-transmission from 115,000 volts through 500 kilovolts typically. There's very few circuit models being built. There's a lot of load being added. And what the battery does is it addresses both the ability to arbitrage power and supply local T&D support. And Howard and I wrote several, actually, technical papers on this in 1990, 1991, using photovoltaics and energy storage for grid support. I wrote a paper with a former colleague called The Distributed Utility in 1991 that basically outlined a model for how distributed renewables but also storage would help support the grid and now that battery is available at huge scale extremely affordable what we're seeing um is also batteries transitioning from five years ago these batteries were one hour typically you know a few years later they were two hour now with this stuff coming on on the grid is four hours well the customers we were speaking to last week, we're seeing a lot of six and eight hour applications. And so we think the batteries are really important for customers to connect close to the grid, but also highly synergistic with solar, which is why we're bullish on the long-term forecast for solar, because the costs have come down so much. The only impediment is basically more duration and dispatchability, and the storage is solving that. And actually, we just saw also an analysis that the Arizona Public Service put forward in a, I believe, a regulatory proceeding, looking at what's called the ELCC. It's the Effective Load Carrying Capability. And solar by itself was pretty low. Solar storage was very high, kind of right up there with gas and so forth. And so the storage is essential as we go forward. And we see previously unimagined use cases for it as we go forward. And it really portends well to solar. And I'll just, the final thing I'll note is the first six months of this year to date, 90% or 91% of the power generation brought online in the United States, even in this regulatory environment, 91% was solar and storage. So, and we could speak to you all day long about why solar is going to keep coming down in cost and keep improving in availability and similarly with storage. So we're very bullish on the prospects of these technologies to continue growing. Next question.

And your next question comes from the line of Ben Callow with Baird. Your line is open. Please go ahead.
Hey, guys. Thanks for fitting me in. And I'll try to keep the time here. Just, I know we focus a lot on the U.S. Maybe could you talk, you know, internationally, you know, Tracker, Don Tracker, the Saudi JV, and then, you know, because Inver has been such a focus of the call. Could you just talk about, you know, the non-U.S. strategy?
I know you're going to produce in the U.S., but, you know, how you go to market there outside of spain you know i'm thinking more asia there so a couple different questions there but thanks for your time guys yeah sure first i'll talk about uh nx arabia which um we banged the gong in january of this year they're off to a great start we've booked business there through the jv it's a structural change uh in how we report the financials there we're not recognizing the revenue. But we are recognizing the profitability of the venture, and we do have a license there. So it's good for the company, and it allows us to get our technology there and be very competitive in that low-cost region. And so that's been a very good, we're very happy with the leadership there and our partner in Abu Nayyan Holding Company, just an excellent partner for us in NX Arabia. And they're addressing many countries in the region, not just Saudi Arabia, but in MENA, Middle East, North Africa, we're working closely with them there. And then as far as the international business, we talked about Zimmermann, which is this very well-respected German company. They've been around for about 15 years. Very well-respected Brown, great team, headquartered in Germany. To be honest, Next Power doesn't have much footprint. Germany historically has been a very strong market in Europe. It's one or two over the last 10 years. We don't have a lot of footprint there because it's largely a fixed tilt market. And Zimmermann has a very clever, excellent fixed tilt system and a significant market share in Germany. And they're adding 15 countries to our 50 country market footprint. So we're expanding our market, much of that in Europe, which in in totality, is as big as the U.S. business in terms of, or as much as the U.S. generating capacity, that's what we see in Europe. So in totality, it's a very significant, important market there. So with Zimmermann and our expanded team in Madrid, and then we have others from the Ziger Apex acquisition for the inverter there in Spain. So we've just greatly expanded our footprint in Europe and internationally. Thanks for the questions, Ben.
So this brings our call to a close. For those of you that didn't get a chance to answer a question, please join us on the callbacks and we'll unpack those. We'd like to thank our customers and partners for their continued trust, our employees around the world for their incredible work, and our shareholders for your confidence and support. We're really excited about these opportunities ahead and believe our market leadership, expanding technology platform and outstanding team position us well for the future and look forward to sharing more with you at our Capital Markets Day in November. Thanks for joining our call and have a great day.
